First, When I commit characters to a story as the defender do these characters exhaust?

Second,if I commit characters to a story in my story phase and my opponent commits zero characters do the icon struggles still resolve (for example the arcane and the investigation)?

Last,when I commit a character with 1 skill and one investigation icon to a story during my story phase and my opponent commits zero characters , how many success tokens I will put to the story?

Thanks in advance!

In order to commit characters to a story, you must exhaust them (unless there is a card effect that states otherwise)

If your opponent has 0 characters committed, all struggles still resolve (unless there is a card effect that states otherwise)

If you commit your Laboratory Assistant (the 1 skill 1 I character I assume you're talking about) and your opponent commits no one, then you get 3 success tokens (unless there is a card effect that states otherwise)
